Pramipexole Enhances Reward Learning by Preserving Value Estimates
Halahakoon, Don Chamith; Geddes, John R; Cowen, Philip J; Harmer, Catherine J; Browning, Michael (2022-01)Background: Dopamine D2-like receptor agonists show promise as treatments for depression. They are thought to act by altering how individuals learn from rewarding experiences. However, the nature of these reward learning ... -
Precision biomarkers for mood disorders based on brain imaging
Capitao, Liliana; Harmer, Catherine J (2020-10)Mood disorders are a global public health problem because of their high prevalence, chronicity, and recurrence throughout the lifespan as well as increased risk of mortality.123 They also impose a heavy economic burden on ... -
Predicting treatment response in depression: the role of anterior cingulate cortex
Godlewska, Beata R; Browning, Michael; Cowen, Philip J; Harmer, Catherine J (2018)Background: Identification of biomarkers predicting therapeutic outcome to antidepressant treatment is one of the most important tasks in current research because it may transform the lengthy process of finding the right ... -
Predicting Treatment Response to Antidepressant Medication Using Early Changes in Emotional Processing.
Browning, Michael; Goodwin, Guy M; Harmer, Catherine J (2019-01)Antidepressants must be taken for weeks before response can be assessed with many patients not responding to the first medication prescribed. This often results in long delays before effective treatment is started. ... -
Pro-dopaminergic pharmacological interventions for anhedonia in depression: protocol for a living systematic review of human and non-human studies
Ostinelli, Edoardo; Browning, Michael; Cipriani, Andrea; Harmer, Catherine J (2023-10)Anhedonia is a key symptom of depression, and it has been suggested as a potential target for future individualised treatments. However, much is unknown about how interventions enhancing dopaminergic pathways may affect ... -
Resting state functional connectivity patterns as biomarkers of treatment response to escitalopram in patients with major depressive disorder
Harmer, Catherine J; Godlewska, Beata R (2021-09)With no available response biomarkers, matching an appropriate antidepressant to an individual can be a lengthy process. Improving understanding of processes underlying treatment responsivity in depression is crucial for ... -
A single administration of ‘microbial’ D-alanine to healthy volunteers augments reaction to negative emotions: a comparison with D-serine
Capitao, Liliana; Harmer, Catherine J (2020-03)Background Activation of the glutamate N-methyl-D-Aspartate receptor (NMDAR) with its co-agonist D-serine has been shown to improve subjective mood in healthy volunteers. D-alanine is another potent NMDAR co-agonist which ... -
A single dose of fluoxetine reduces neural limbic responses to anger in depressed adolescents
Capitao, Liliana; Chapman, Robert; Murphy, Susannah E; James, Anthony; Cowen, Philip J; Harmer, Catherine J (2019-01-21)Depression in adolescence is frequently characterised by symptoms of irritability. Fluoxetine is the antidepressant with the most favourable benefit:risk ratio profile to treat adolescent depression, but the neural ... -
Statins for major depressive disorder: A systematic review and meta-analysis of randomized controlled trials
De Giorgi, Riccardo; De Crescenzo, Franco; Cowen, Philip J; Harmer, Catherine J (2021-03)The burden of depressive disorder is large and new treatment approaches are required. Repurposing widely available drugs such as statins may be a time- and cost-effective solution. Statins have anti-inflammatory and ... -
Statins in depression: a repurposed medical treatment can provide novel insights in mental health
De Giorgi, Riccardo; Cowen, Philip J; Harmer, Catherine J (2022-08)Depression has a large burden, but the development of new drugs for its treatment has proved difficult. Progresses in neuroscience have highlighted several physiopathological pathways, notably inflammatory and metabolic ... -
Subchronic treatment with St John’s wort produces a positive shift in emotional processing in healthy volunteers
Cowen, Philip J; Harmer, Catherine J (2018-11-28)The neurocognitive model of antidepressant treatment in depression states that antidepressants work by producing relatively immediate positive shifts in emotional processing, which translate into clinical improvement with ... -
Subclinical anxiety and depression are associated with deficits in attentional target facilitation, not distractor inhibition
Harmer, Catherine J (2019-06)Mood and anxiety disorders are associated with deficits in attentional control involving emotive and non-emotive stimuli. Current theories focus on impaired attentional inhibition of distracting stimuli in producing these ... -
Symptom Dynamics and Attention in Depression: Fatigue and Low Positive Affect are Associated With Reduced Orienting Efficiency
Harmer, Catherine J (2022-02)Depression is a heterogeneous mental disorder involving a complex interplay between potential etiological and maintenance factors. The current study examined how depression heterogeneity is related to attentional ... -
Translating the promise of 5HT4 receptor agonists for the treatment of depression
Murphy, Susannah E; De Cates, Angharad N; Gillespie, Amy L; Godlewska, Beata R; Scaife, Jessica; Wright, Lucy C; Cowen, Philip J; Harmer, Catherine J (2020-02)Animal experimental studies suggest that 5-HT4 receptor activation holds promise as a novel target for the treatment of depression and cognitive impairment. 5-HT4 receptors are postsynaptic receptors that are located in ... -
Value of monitoring negative emotional bias in primary care in England for personalised antidepressant treatment: a modelling study
Harmer, Catherine J; Goodwin, Guy M (2019-11)Depressed patients often focus on negative life events. Effective antidepressant therapy reverses this negative emotional bias (NEB) within 1 week. Clinical therapeutic effect usually requires 4–6 weeks. The value of ... -
Variation in recognition of happy and sad facial expressions and self-reported depressive symptom severity: A prospective cohort study
Harmer, Catherine J (2019-06)Objective:Cognitive theories suggest people with depression interpret self-referential social information negatively. However, it is unclear whether these biases precede or follow depression. We investigated whether facial ...
